awesome, thanks for the pointers re: sha, will take a look! also WRT to delving, i totally understand. these discussions can take a lot of effort. from my side, im simply trying to avoid needing to be in all the chat rooms following all the discussions, so would rather have it one place in the public sphere. like i said on delving, in the short term im happy to have discussions here to plug my gaps, and then translate it back to delving; just be charitable if i fuck up the explanation, its certainly not malicious 😄
